The modern bridal shower stems from the time when a bride's family was expected to provide a trousseau bride. The trousseau was comprised of clothing, lingerie, accessories, and various housewares. So in effect, pretty much everything a bride gets at her bridal shower nowadays.
This treasury is full of gorgeous lingerie every bride should add to her modern trousseau :)

Fat Bottomed Girls doesn't have anything to do with anything...except that there are underpants in this, and presumably an above average posterior would also need ample coverage.
